Introduction
This technote explains step-by-step procedures on how to configure and use Wonderware®'s
ABDHPlus DAServer to access data in a PLC connected to a Data Highway Plus network. This DAServer
can provide connectivity to the Allen-Bradley families of PLC-5 and SLC 500 controllers, which are
connected to the Data Highway Plus network.
The DASABDHPlus is setup on a computer using the Windows® 2000 Operating System.
We will try establish the communications to a SLC504 PLC as an example.
Before you continue, make sure you do the following:
Install and configure the PLC. You will need the Rockwell Software RSLogix 500 to configure the
SLC504 PLC.
Read and follow the instructions in the ABDHPlus DAServer's readme file and related documents
for System requirements, proper installation procedures, and supported Operating systems.
Install the latest version of the ABDHPlus DAServer. If a previous version was installed, be sure
to uninstall it using Add/Remove Programs in the Control Panel.
We will use the Wonderware’s WWClient utility to test the communications between the
DASABDHPlus and the PLC. You can get a copy of the WWClient from an I/O server CD or you
can also download it here: WWClient Utility.
This technote is written using ABDHPlus DAServer version 1.0.100. To check the version number of the
server, use Control Panel/Add/Remove Programs - select Wonderware ABDHPlus DAServer, then
click on Support Information.
Note: This technote assumes the user has a basic working knowledge and understanding of Data
Highway Plus (DH+) networking, Allen-Bradley software/hardware, Microsoft® operating systems,
Wonderware FactorySuite® components, WWClient utility, and the ABDHPlus DAServer.
If you have problem configuring the 1784-PKTx adapter or the PLC, please contact Allen-Bradley for
assistance at www.ab.com.
Configurating the 1784-PKTx Adapter
1. Install the 1784-PKTx adapter onto a PCI slot in your computer.
Note: It is important that the adapter is installed on the computer before the ABDHPlus
DAServer.
2. Verify that the Memory Jumper (JP2) on the card is set to the 32-bit position. If it is on the 1
Meg position, move the jumper to the 32-bit position.
3. Make sure the card ID jumper (JP3) is set correctly. For a single card, set it to ID number zero
(0).
4. Connect a known good DH+ blue-hose cable from the 1784-PKTx adapter to a DH+ port on the
PLC. Make sure to assign a valid Data Highway Plus node address to the port. You will need the
Rockwell Software RSLogix 500 to configure the SLC504's DH+ port.
5. Turn on the computer. The Windows 2000 Operating System will recognize the 1784-PKTx

16. Install the DASABDHP DAServer.
17. Click the Start button on the Windows taskbar to launch the System Manager Console.
18. Select Programs/Wonderware, then select System Management Console.
19. Click DAServer Manager.
20. Expand the ArchestrA.DASABDHPlus.1 icon, then highlight Configuration.
The following window appears:

8/22/13
F IGURE 9: ARCHESTRA SMC
• Device Group Update Interval: Specifies the update interval of the default device group.
• Slow Poll Interval: Specifies the interval the DAServer polls the field device after it goes into
slow poll mode when connectivity problems occur.
• Transaction to Subscription Ratio: Transactions are poke/read messages from a DDE/SL/OPC
client. Subscriptions are messages generated by items being on advise, and they are sent
periodically at the Update Interval. The Transaction to Subscription ratio defines the maximum
number of transactions the DAServer sends before sending one subscription.
• Transaction Message Timeout: The timeout for transactions (read/write/refresh/property)
per message. The timeout has to be set in such a way that the data acquisition on a message
does not take longer than this timeout.
• Server Protocol Timer: Disabled.
• Diagnostic Backlog Size: Specifies the maximum number of transactions shown in the
Transactions diagnostic root.
• Poke Mode: The following modes are available:
- Control Mode preserves the poke order without folding.
- Transition Mode preserves the poke order with minimum folding by keeping the first, second and
last poke values of an item.
- Optimization Mode does not preserve the poke order and has maximum folding by only poking
the last value of an item.
• Case Sensitive: Controls how the DAServer scans item and device group names with respect
to upper/lower case.
• Device Group Cache: This parameter is for future use.
• Simulation Mode: Disabled.
• System Items: This parameter controls whether the system items appear in the browse

interface and if they are recognized as valid ItemIDs by the DAServer's data acquisition
interfaces.
• Unique Device Groups: This parameter controls whether the device group names are checked
for uniqueness across all device nodes of a DAServer.
21. Select and then right-click Configuration.
22. Choose Add_PKT_CARD Object.
F IGURE 10: ADD_PKT_CARD OBJECT
The New_PKT_CARD Parameter dialog box should now appear as shown in the figure below:
F IGURE 11: NEW _PKT_CARD PARAMETER
Where:

• DH Plus Node Address: is the node address for the adapter displayed as an Octal number. It
should be a unique node number in the Data Highway Plus network.
• Firmware Path: is the location of the DASABDHPlus (copied) firmware files.
Normally it is C:\Program Files\Wonderware\DAServer\DASABDHPlus\Bin\Firmware.
• PCI Card: Will display the card number if the DASABDHPlus recognizes the 1784-PKTX adapter.
23. Change the DH Plus Node Address to the one assigned for this card.
In this test, they are assigned number 77 (node address).
24. Select and then right-click on the New_PKT_Card_000.
25. Select Add SLC500_DHP Object:
F IGURE 12: ADD SLC500_DHP OBJECT
The New_SLC500_DHP_000 will be added to the tree.
The New_SLC500_DHP_000 Parameters tab field should now be similar to the following figure:
9/14
8/22/13
F IGURE 13: NEW _SLC500_DHP_000 PARAMETERS
Note that the DH Plus Node Number in the above dialog window is the PLC's Data Highway Plus
node address.
26. Now, select the Device Groups tab.
27. In order to add a new device group (or topic), right click anywhere in the white space of the
device groups window, and select Add.
28. Change the device group name to a meaningful one such as SLC504 as shown in the following
figure:
10/14
8/22/13
F IGURE 14: ADD DEVICE GROUP NAME
Now, we're ready to run the DASABDHPlus server.
29. Right click ArchestrA.DASABDHPlus.1 and select Activate Server:
F IGURE 15: ACTIVATE SERVER

Testing the Communications
You can now test the connections to the PLC. We will use the WWClient utility for the test (click
here to download).
To launch the WWClient:
1. Click Start/Run from the Windows taskbar.
2. Enter WWClient to launch the Wonderware WWClient program.
3. Select Connections/Create from the main menu bar.
The Create Connection dialog box appears.
4. Enter appropriate information as shown in the following figure:
F IGURE 17: C REATE C ONNECTION
12/14
8/22/13
Where:
• Node: is blank since the DASABCIP and the WWClient are on the same computer. Otherwise,
enter the computer name of the machine running the DAServer.
• Application: DASABDHPlus, which is the application name of the DAServer.
• Topic: SLC504, which is the exact name of the new device group we just created in the
DASABDHPlus's device groups window.
• Connection Type: IOT - the SuiteLink protocol used for this technote.
5. Click Create and Done.
The WWClient window should appear similar to the following figure:
F IGURE 18: WW C LIENT C LIENT C ONNECTION
6. Now, select Item on the main menu bar.
7. Enter a known good PLC register address.
Note: The following figure (Figure 19 below) shows an example of WWClient successfully
advising item S:42 from the PLC.
8. Click the AdviseEX button to register and advise the item.
If the Ethernet connection to the PLC is good, you should see the value for the register S:42
changing (following figure):
